Should we judge people on their music (like Justin Bieber, One Direction,etc.,)

These results are horrible...lets say you were a singer and you wrote a song and people didnt like it...sooner or later people HATE you...sending you nasty tweets, making rude comments and even death threats all because of a frickin SONG! That what people are doing to performers!! Quit it! No need to hate! What did they EVER do to you!? STOP THE HATE! Please!
